Sophie Tweed-Simmons is shutting down critics who have accused her lingerie campaign photos for Adore Me of being altered.

“For those saying this is Photoshopped, well you’re wrong,” the model, 23, posted onInstagram along with a photo from the campaign in which she wears a matching gray bra and thong. “I was not altered to be smaller or bigger.”

Tweed-Simmons – who is the daughter of Gene Simmons and Shannon Tweed – says she is constantly being criticized for her body, but still feels confident exactly the way she is.
